This oil and air seperator can be used on stock cars to cars that are highly modified even with superchargers. What does it do? It reduces oil retention by the engine and reduces knock. Essentially, better for your motor assisting longevity and acting as a preventative measure. From Weistec, "As the excess crankcase pressure is vented through the PCV valve and into the intake manifold the engine will eventually draw in, not only air which is wanted, but also particles of aerated oil which creates instability in power due to the low octane level of oil."

Key Features:

Eliminates the anti octane properties of oil

CNC machined 6061 aluminum

Hard anodized to military spec

Direct bolt in for M156/M159 vehicles

Utilizes brass filter elements

100% serviceable

Flexible and reversible mounting and installation

Pictured below is a typical intake manifold from an M156 engine after 8,500miles (13,700Km). It is very clear the amount of oil that is being drawn in by the engine.

Sorry about reviving a dead thread...but I got mine installed today for 200 bucks, not that bad. But I had a question: where should the catch actually sit? He installed it kind of behind the passenger headlight. Should it be closer to the engine block itself or towards the back or does it not matter? Thanks! I'll post pics if needed but I don't think it's necessary...he did do a really good job though.

Did you get a bracket made? Mine would only fit there although I didn't install as I am disassembling the motor soon so might as well do it the easy way. Would love to see pics.
